This will take a bit of explanation:
1. The dishwasher was not getting the dishes clean.
2. I measured heater resistance - heater was dead.
3. I replaced the heater. Case closed, I thought- but dishes were still not clean.
4. With voltmeter, I can see that heater is getting voltage and working. Trouble found: The water does not fill enough during the fill cycle to trigger the "full" sensor (the float). The heater is not in good contact with the water because water is not high enough. I suppose this is why the first heater died - it got too hot and burned out, because it was in poor contact with the water.
5. I disconnected the supply line at the fill valve and ran it into the sink. There is good pressure there. I checked for blockages in the line from the fill valve to the dishwasher tub. No problem.
6. I energized the solenoid, and water flows out at what seems like a reasonable speed, but I guess it isn't enough to fill in time. On the timing sheet it looks like the machine goes on to the next cycle after 1 min, 35 seconds, whether or not the float switch has switched. If I blow into the fill valve when energized, I can get some air through, but it isn't a lot. If the fill valve is not energized, then I cannot blow anything through at all - as expected.
Question: How much resistance should I expect from the fill valve when blowing through it? What else can I do to correct/define the problem? Do I need to replace the fill valve? Is there any way to lengthen the water fill time? I think that another minute would be enough - it's not like it is very far from being full enough.
